chore: Add git-cliff as a changelog generation tool

Changelogs will be generated using commit messages by
`scripts/release.py`.

Both the commit message and the PR title should follow https://conventionalcommits.org. E.g. start with 'feat:' (for Features / Changes), 'fix:' (for Fixes), 'api:' (for API-Changes), 'api!:' for breaking API-Changes) 'refactor:' (for Refactor), 'perf:' (for Performance), 'test:' (for Tests), 'style:' (for Styling), 'chore:' (for Miscellaneous Tasks)
